Why does my fluorescent light flicker when I turn it off?
Without a properly operating ballast to limit the light’s current, a fluorescent lamp connected to the electrical source would quickly and uncontrollably increase its current flow—causing the lamp to burning out. This is why a degrading ballast will cause the fluorescent lights to flicker.
What does it mean when a light bulb flickers when turned off?

Why are the lights in my house suddenly flickering?
